Apparently if you hit ` (that's the 'left single quote' underneath tilde (~/`)) it opens up some kind of broken help screen.
It's not major, just annoying. I didn't see it come up when other characters are hit while the page is active.. hoping that you might adjust whatever may have changed so that the ` key stops doing weird stuff. For now I'll just see if I can block the script.
I have a remap with autohotkey which makes use of this button, but the screen will come up if I'm closing a tab in chrome, and the next tab is an imgur image-page link.
